R-Guard Installation Detail-Interior Air and Water Seal on Wood Construction - Prosoco

Position the window 'plumb, level, and square' into the prepared opening. Apply AirDam as the interior air sealant, ensuring it's compatible with the treated opening and forms a durable, watertight seal. AirDam blocks bulk water and moist outside air, preventing conditioned indoor air from escaping around the window. This integrates the window into the broader air and water management system, preventing water from entering the conditioned space.

• Position Window: Ensure the window is 'plumb, level, and square' when installing it into the prepared rough opening
• Apply AirDam: Use AirDam as the interior air sealant to ensure compatibility with the treated rough opening and create a durable, watertight seal
• AirDam Protection: AirDam prevents bulk water and moist outside air from entering, and conditioned indoor air from escaping around the window
• System Integration: This ties the window into the larger air and water management system, preventing water from entering the conditioned space
• Joint Size Guidelines: Sealant depth should be half the width of the joint, with a maximum of inch (13 mm) and a minimum of inch (6 mm). Minimum joint width should be inch (6 mm)
• Joint Backing: A properly sized non-gassing polyethylene foam backer rod should compress by 25-30% when installed. Install backer rod by compressing and rolling continuously into the joint channel without stretching or puncturing
• Installation Steps: Install a continuous bead of AirDam without gaps or air pockets. Tool immediately with a dry spatula to ensure complete wetting of the joint bond surface and produce a smooth, concave joint profile. FastFlash wraps into the rough opening in the structural wall
